GEORGE A. W. RUSHWORTH, OF WITHINGTON, ENGLAND.

PRINTING-STAMP.

Specification of Letters Patent.

Patented Jan. 27, 1914.

Application filed March 29, 1913. Serial No. 757,615.

To all whom it may concern:

Be it known that I, GEORGE ARTHUR WIL- LIAM RUsHwoRrH, a Britishsubject, residing at Withington, county of Lancaster, England, haveinvented certain new and useful Improvements in Printing-Stamps, ofwhich the following is a specification.

This invention relates to self-inking printing stamps in which the typebed is carried in a movable frame and held normally against the inkingpad by a spring and turned over and away from the inking pad by thedepression of the handle for the operation of printing, the inking padbeing removable and replaceable to facilitate the re-inking of the typebed or toprint in different colors.

The invention consists in the details of arrangement for mounting theinking pad and retaining it in position.

The invention will be fully described with reference to the accompanyingdrawings.

Figure 1. is a perspective view of the selfinking stamp showing theremovable ink pad in position. Fig. 2. is a transverse section of same.Fig. 3. is a transverse section showing the ink pad separate from thestamp and ready for insertion therein. Fig. 4:- is a transverse sectionshowing the ink padwithdrawn. Fig. 5. is a transverse section showingthe ink pad in position for inking. Fig. 6. is -a longitudinal elevationof same.

The main features of the self-inking stamp comprising the stand A whichcarries the ink pad B, the reciprocating frame C which carries the typebed D, and the means for pivotally mounting the type bed are of the,ordinary construction.

In carrying out the invention instead of affixing the ink pad B to thestop of the stand A as is customary, I make the stand A with transverseslides or guides a at both ends, and I make the ink pad loose orremovable therefrom, to rest upon the slides a and so that it can bereadily slid into position in the stand between the top of the stand andthe slides a, for the purpose of inking the stamp or type bed D, and canbe readily withdrawn for the purpose of applying a fresh supply of inkthereto.

The soft ink pad B is mounted on a detached plate, frame or tray 6 toslide into position along the grooves formed by the guides a, and isprevented sliding back by a turn button a or other catch. The plate Z)is provided adjacent its inner or rear corners with pins or trunnions Z)and the guides at are turned over or formed with hooks or stops at attheir front extremities to prevent the complete detachment of the inkpad B at one side of the stamp when withdrawn, and to enable it to beswung upwardly at such side, upon its trunnions as pivots, into theposition shown in Fig. 5 to receive a fresh supply of ink.

The ink pad B is so arranged that it may be completely withdrawn anddetached at the side of the stand A opposite to the stops (4, so thatthe pad may be interchangeable for different colors.

The ink pad B may be made for a single color ink or it may be dividedeither longi tudinally or transversely by one or more strips or bars ofmetal, rubber or other suitable material into separate compartments intowhich the absorbent material is fitted to present two or more colors forinking the stamp.

The invention is designed either for hand stamps or to be applied tosimilar stamps when used in conjunction with copying and duplicatingmachines for the purpose of duplicating in two or more colors.

What I claim as my invention and desire to protect by Letters Patent isIn a printing stamp, the combination, with a stand, a reciprocatoryframe mounted therein, and a type bed carried by said frame; of a pairof horizontal guides secured within said stand at the top thereof andhaving their front ends bent upwardly to form stops; and an inking padslidably mounted upon said guides and provided adjacent its rear cornerswith trunnions arranged to travel along said guides and into engagementwith said stops during the outward movement of the pad, to limit suchmovement, said pad being designed to be swung upwardly into verticalposition upon said trunnions as pivots when the trunnions are soengaged.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
